In real life in nasty windy/wet conditions? Surely the generator due to the endurance outer being rather more weather resistant. PL holds up to saturation quite well but does still lose a fair bit of warmth, and you'll have losses from very strong winds too.
In dry conditions, goodness knows
Alternative is the Haglofs Barrier hood. Just bought one as i don't like the look of next years replacement, and already owning the barrier (hoodless jacket) i know its excellent. The fabric is thermolite which is an alternative, but superb option, to primaloft and it is 150g in the body and 100g in the hood & sleeves. My new medium weighs under 600g and packs down into its pocket and is pretty compact. The hood is fairly big though, although my nappers tiny, it has adjustment on it. Got it from here and they are open to negotiation as i got mine down quite a bit as they price matched another online shop. Consider it you won't be dissapointed
IIRC the Barrier hood was the highest TOG - 3.6? in insulkated jacket review in last winters trail magazine.
I wanted a PL1 jacket it was choice between alpine or the OLD Photon. beeing tight...I mean carfeful I got the Photon for £50.
If I had to choose on specification for scottish Winters I would choose the Alpine for the PL1 and Shell fabric.
The ME Citadel may be warmer still? I lust after that but as my wife is already 'concerned' about my outdoor coat collection and the price is high.... alas not this year.
I owned a Generator Alpine and the new Photon Jacket simultaneously for a short while, and ended up keeping the Photon.
In still, dry conditions it is undoubtedly the warmer of the two, the loft being noticeably greater, especially in the arms. However, the Endurance outer of the GA would perhaps even things up given a bit of wind and rain.
I have not run such a deep research I must admit.
I was looking for a warm jacket while staying outside and Ibought the Photon Jacket
In the case of rain, I use my waterproof hard shell on top of everything.
Hence I don't know if I should realy care about the water resistance of my insulated jacket.
Mountain Equipment Fitzroy as an alternative?
I looked at it recently, it's brilliant. £100 I think on OutdoorShop.
